Be it known tllfttl.,-i0l-1N Frmsruie Ross, 1.1onufacturer, e subjr t ol the King of Grout- Britein, residi city of Toronto, in

iork, in the Province of Gnterio, Canada, have invented certain new and useful Improvements in Cons, of which the following is a speeilicugiiom v l My invention. relates to improvements in. cans; the objects of my invention are, first, to construct a cheap and simple can that may be hermetically sealed; sew idly, to strengthen. the seam or oint so at prevect cracking; of some" thirdly, to expel as much air as possible m the can before some is hermet cally see l, and,fourthly,-to provide aporticularlicl; iLiKi itcousists,csseulislbgof a. cell-body made of sheet meta and provided with e bell-shaped mouth, the upper portion 01: said-can for the r uniformly stretched, that the diameter of the can at its stretched portion will be greet-er than the diameter of the can. at its unstretclled portion, the join t or seam filled with soldering material, and bottom mode of sheet motel suitably secured to said earn-body. In the said con-body Ii preferably stamp out there'- from and over the some or joint at lug, so as to ail'ord brace w cli will 5 "event cracking or splitting'cl tl" nrleriu said joint or see m during manufacture ol' the coir-body.

My invention also consists in the particulair coustructioribl the lid hereinafter dc-- so dering material H thereof being shown in vertical section. -2 1s a portion of a horizontal cross-section on scribed.

In the drawings like characters of reference indicate corrcsioudirig parts in each i gures A. is the con- Orly, mode of sheet metal and having its ends secured together in any of the Well-known manners As shown in the drewred distance being provid:

ings, the ends are secured together by Lin: usual outside lock-seam B. i

Referring to Fig; 5, it will be seen that the corners a of the sheet of metal (I, out of which the can -body is referebly formed are cut away, so that there will only be one thickof metal at the point D of the seam, so that the besding E may be there properly formed. Of course this construction just described will also be embodied in the bottom of the can. The con-body is provided with a bellslice-ed mouth P. which may or may not be provided with the beading E. In order to make tie joint or seem G flush with the inner surface 01 the can, fill some with suiteble soldering material H and remove the surolus soldering material, so that the said J s or seem will be flush with the inner 'surlure of said cswbody. During the removal of tretch the up- 1' a suitable disbe? the boll-shaped mouth downward, LS to insure e true sealing-surface when the .d is inserted 'th erewithin; The can-body Ais .Wit-h the bell-she ed mouthFbefore it is stretched, es describer and it will be undorstood that curing the stretcliing'operetion the adjacent ends of the sheet metal at the point D will not be subjected to this strain by reason of'said bell-sliaped mouth, thus movent'og any cracking or splitting in the joint ise ping from said point D downward. Fr i this it will be understood that the diane oily constru c ted Without the bell-shaped mouth .l", the oiul; or seem at the point D would be directly in the stretching force, thus causing them to separate and split the joint or seam. In order to prevent any possible chance of the soldering inoterizilll filling the joint or sea-In G from being cracked or split during the manufacture of the can-body, 1 stamp out from said canplane of the body in that portion of the can where the greatest bursting strain is applied a lugL' whlch acts as a brace. This lug I forms cavity in'the joint or seam and same course is filled with the soldering material,

thus enabling me to increase thevolume of.

seam. This lug I of course may be'of any The stamping out of The lid or cover K, I use with my can conslsts of the top L, provided on its edge with a flange M, which overhangs a vertical flange N, which is provided with a horizontal outwardly-projecting flange O, which in turn is provided with a vertical flange P, which may e of any suitable depth. If desired, the lower edge Q of the flange I maybe slightly turned inward, as shown. The worked parts 'or portions of the sheet metal in the lid or.

. greater than the internal diameter oi stretching of the upper of said can-body A will be further stretched,

and thus assume approximately the shape shownln Fig. 1. As the flange P of the lid orcover K is particularly hard, there is no possible danger of same being crushed inward.

, It will be understood that the surplus soldering material H filling the joint or seam G need be removedonly for the distance the flange P is in contact with the can-bodyA.

The flange P is provided with a small hole 0 just below the lower edge (1 (shown by dotted lines) of the sealing-surface e of said flange, which extends approximately in depth from the shoulder h down to the dotted line d on the outer circumference of said flange.

It will understood that there is always more or less air imprisoned within the canb'ody A during the insertion of the lid or a cover K thereinto, and in order to rcmove'as much as possible of this air before the can is i hermetically sealed I provide the said hole 0.

The air within the can-body will of course be held between the top of the contents in said, can-body and the lid K, and during forcing of said lid home'a great portion of the imprisoned air will be forced out oi the hole a and between the flange I and the can-body.

. with any suitable bottom; but'in order to reduce the pressure of the air, within said can'- hloldy it is impossible for me to remove I con- ,gtma said 'can-body with a flexible bottom ,lthe normal ositlon of which is shown in dotted lines. 'en] the 'lid or cover'K is forced home, the said-flexible bottom U will bulge out inthe position shown, thus providing additional "rooir'gwithin said can-body, and 'thus reduce to a minimum the back pressure a ainst the lid of the imprisoned air.

Taking" the dotted. line d as bein the depth'of the sealing area, I extend the flange P below said sealing area, so that the portion of said flange. therehelow will-"provide a means for givmg said ,lid or cover proper support within the can-body, so that it will be easier inserted andbetter supported and not liable to be pushed sidewise and jammed.

U on referring to Fig. 1, it will be seen that the iameter of the top L of the lid or cover is sufficiently less than the diameter of the top of the can-body, so as to form an annular groove 11., in which is inserted the'mean's' for removing the lid or cover. o

It will of course be understood that the expansion of the can-body A (shown in the;

drawings) is much exaggerated. I

Upon referring to Fig. 1 it will be seen that I preferably stamp out the lug I so that it will be midway the depth of the sealing area e. When the lid or cover K is shoved home, top of same is on a level with the! upper edge, of the can-bod A. During the construction of the can-b0 yan outwardly-formed annular shoulder i is formed therein, and same will of course.be below the lower edge Q of'the flange P. Of course the flange Q may abut against the shoulder '01; but this is immaterial.

Ofcou-rse during-manufacture of the bellshaped mouth F the portion of the can-bod that forms the bell-shaped mouth is stretche but the subsequent stretching of the canbody occurs from the bottom of said bellshaped mouth downward.

Obviously the longitudinal diameter of the lug or brace I is laced approximately at right angles to the oint or seam G.

' I do not confine myself to the construction. herein shown and described, as same maybe altered in various ways without departing from the spirit of my invention.

What I claim as my invention is 1.
